FRANK nUMunL, or NEWTON, IOWA.

cuw'snn- To all whom it floaty concern:

Be it known that I, FRANK HUMMEL, a citizen of the United States, residing at Newton, in thecounty of Jasper'and" State of lowa, have invented certain new and useful Im- 'provements in Culverts, of which the followgether when the culvert has been set in the ground by the mechanisms which I have pro- Vided.

It is also my object to provide a protector for the ends of the culvert, designed to prevent the dirt getting into the openings at the ends, and also to provide means forpreventing the culverts settling at either side of it or from being forced laterally by the pressure of earth upon it.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully pointed out in my claim, and illustrated in the accompanying drawings, in which- Figure 1 shows in perspective the complete culvert as set up. Fig. 2 is a sectional view of the culvert. Fig. 3 is a sectional view of the modified form of the culvert; and Fig. 4 is a modified form of the culvert, part of this view being in section. Fig. 5 is a detail view of a modified form of the device,

- showing the same means for securing the secv the upper portion of tions together as is used for securing the parts of each section to each other.

Referring to the accompanying drawings, it will be seen th t there are a series of sections, each of we chis composed of the 'two parts-10 and 11. The part 11 has a lateral support 12 near its lower outer portion and some distance above of the part 11. The part 10 also has an outwardly-projecting support 13 some distance above the lower outer portion of the art 10. In the upper portion of the part 11 t ereiis a channel 14 provided with short extensions throughout the length of the part. On the part 10 there is a pro'ection 15 extending throughout the entire ength of the part 10 and design to enter the channel 14 to hold he parts 10 and 11.111

' position relative to each other. When these other, an arch is formed by them and an opening between them, which is substantially semicircular at its upper portion. Each of these parts 10 and 11 has a flaring rib 16 at one" end. Two of these sections which are formed of the parts 10 and 11 are placed adjacent to each other, and the bolts 17 are passe through the ribs 16 of one section into them 16 of the adjacent section to secure these sections in position relative to each other. On the middle sections there is a rib 16 on each of thesections, so that the sections may be rigidly held together by the bolts passing through the ribs. At the ends of the outersections there is a protector 18, which extends upwardly a considerable distance from the outer ends of these outer sections, so arranged that they will prevent the dirt, which is placed on top'of the culvert when completed, from getting into the opening formed by the culvert. When all of these sections are attached together in the manner above indicatedthat is, the parts 11 and 12 projections 15 in the channels 14, and each section connected with the section adjacent to it by means of the bolts 17 passed through the adjacent ribs 16, as shown in Fi 1the culvert may be placed in a hole w iich has been dug for the purpose and the lower ends 19 and 20'of the parts 10 and 11 of the sections placed in channels dug in the gr'olfnd' at the bottom of the hole in such a way that the supports 12 and 13 willrest on the ground.

which it is maintained after it is covered by earth and accomplishes the usual results obtained by the use of culverts.

In setting up the culvert the channels for the lower ends 19 and 20 are dug in the earth at the bottom of the lfole made for the culvert, and the culvert is set up insections, and the sections are then attached to each other and the earth thrown upon these sections. The parts of these sections are preferably made of cast metal, the parts 1 I ing cast in one piece and then attached together and the sections attached to each other by the bolts. However, I do not limit myself to the use of metal, as various forms of material may be used in the construction ofmy culvert. v V In the modified form of the device, as shown in Figs. 3 and 4, the sections are made 1 and 12 beparts are properly positioned relative to each of the sections are connected by placing the j Then the culvert will be in the position in 4 of metal and have the two parts 21 and '22 corresponding tothe parts 10 and 11, re-

727 is also attached to the outer spectively, to form the various sections, and these sections are connected with each other by the reinforcing-plates 23, which are attached to the adjacent ends of each of the sections by ineansof rivets 24, and supports 25 and 26 are provided and are attached to the lower ends of the parts 21 and 22, respectively, by means of rivets. A protector ends of the outer sections by means of rivets. These protectors correspond to the protectors 18.

Having thus described my invention, what I claim, anddesire to secure by Letters Patent of the United States therefor, is-

An improved metal culvert, comprising a FRANK HUMMEL.
